LLOIFF is an intermediate file format which exists only in memory. This format is generated by stage 1 of LLO. The design of this intermediate file format must be robust enough that it can handle file formats of all types
lifted to it. For example, PE-COFF (COFF meaning: including OBJ files), ELF, etc.
There can be multiple LLOIFF's at a given time, just as there can be multiple OBJ files in a LIB.
